Twitter has been engulfed in a wave of French anti-Semitic posts using the hashtag #unbonjuif, meaning “a good Jew” in French. The tweets were condemned by French anti-racist and Jewish organizations on Monday.

Typical tweets with the hashtag included phrases such as “A good Jew can pump up your tyre with his nose,” “A good Jew wears a Gucci kippa” or “A good Jew is a dead Jew,” reported Yedioth Ahronoth. Twitter should “take the appropriate measures” to end the “flood of anti-Semitism,” the anti-racist group MRAP said in a statement. Last week France’s Jewish security watchdog SPCJ reported that anti-Semitic acts in France jumped by 45 percent in the first eight months of 2012.
